In the case of high temperature, the crystal water in the gypsum powder evaporates and absorbs heat, and a layer of water vapor is generated on the surface, thereby preventing the spread of fire and playing a fireproof role; an enhanced layer 10 is provided outside the gypsum matrix 9. The gypsum matrix 9 and the enhanced layer 10 are connected by coating glue. The enhanced layer 10 has good compressive strength and flexural strength, which can solve the problem that the traditional gypsum fireproof board has poor compressive resistance and is easy to break; a heat preservation layer 11 is provided outside the enhanced layer 10. The enhanced layer 10 and the heat preservation layer 11 are connected by coating glue. The heat preservation layer 11 has excellent heat preservation performance, thereby solving the problem of poor traditional heat preservation effect; a fireproof layer 12 is provided outside the heat preservation layer 11.

[0035] The working principle of the present utility model: The sound insulation device 4 is installed between the first gypsum fireproof board 1 and the second gypsum fireproof board 2. The fixing plate 3 is installed on the sound insulation device 4, and then the inner bolt 6 is threadedly connected through the threaded hole 5 to complete the fixed connection. There are several through holes 7 on the sound insulation device 4, and a sound insulation layer 8 is arranged in the through holes 7. The sound insulation device 3 weakens the noise through the sound insulation layer 8 in the through holes 7, thereby eliminating the noise.
